mpg on my ka is...

[mike-hkc]

well i just got a single cam with about 250,xxx for 100 .and i notice that it is getting about 5 miles a gallon on the street. and gas gauge keep going up and down what's wrong need help:aw:

[ATLspeed]

major tune up....fuel filter...fuel pump

[pr0ject TRUENO]

ive been getting 20-25mpg on mine :D

[SCato]

ive been getting 27-29mpg, gas prices scaring me, slows me down, no useless reving, and keeping revs low in general

major tune up sounds like is needed

[WagDatto]

Averaged 21mpg on my last tank, even with some stupid revving/driving mixed in with highway.

They hit the nail, /thread.

[irritatedmax]

yeah, start with a tune up. when i got my bone stock 92, i was getting 22-ish mpg's on average with 145,xxx miles on it. i did fuel filter, spark plugs, checked the wires, and other stuff that has nothing to do with mileage but just general maintenance. i have always ran shell v-power (92 octane) through it because it has been proven to clean the engine/injectors. the gas door says use only premium unleaded. anyway, now i am getting 27-ish mpg's in town and 29+ mpg's on the highway with 153,xxx on the car. i am actually impressed with the mileage because my s14 was getting like 13 mpg's with its weak motor.

[mike-hkc]

i just sea foamed it new spraplugs and a new z32 fuel filter

[ms!3]

about 20 in the city and 30 on the highway.

[irritatedmax]

i just sea foamed it new spraplugs and a new z32 fuel filter

any improvement? or let us know after you drive it a bit.

[floodo1]

wow man i get 22 on mixed in town / freeway (in town). and then about 25 on road trips.

i dont see how you guys are getting > 25 on the freeway?
i get the 22 around town cuz i rev the shit out of it all the time. but 30 on the highway HOW??

[5t341tH]

wow u guys make me jealous. mine gets 18mpg around town. thoh it does have low compression and never had a tuneup. whats a full tuneup consist of? i only know the plugs, wires, o2, filters. what else

[irritatedmax]

i drive pretty mildly. few hard corners here and there but no reason to race anyone. stock ka doesn't put up much fight. try babying it for a tank and see if anything changes. $4.00 per gallon is too expensive to waste revving, haha.

wow u guys make me jealous. mine gets 18mpg around town. thoh it does have low compression and never had a tuneup. whats a full tuneup consist of? i only know the plugs, wires, o2, filters. what else

yeah just the basic general maintenance items. i don't think there is a set list but what you said is definitely a good start.

[s14_legend]

20 city/22 highway

[95KA-Turbo]

Yeah I was averaging 26-28mpg on city/highway mix. I definitely get 30 or more on road trips on highway only (like 450 miles per tank). I run 89 octane if that makes any difference at all. I also rev just under 3k....well I try to, a lot of times it'll be around 3500. 97 with all of the emissions and an intake and exhaust (stock header/downpipe and cat).

[240trainee]

I wish my single cam got better milage.

oh well.

it's a pos.

[SHIFT_*grind*]

My SR with a T28 gets ~28mpg on the highway. I was pretty shocked when I realized it.

Do you have a fuel leak? The only thing I can think of that would cause you to get five mpg would be if your gas is just leaking out the bottom of the car. Check all your lines, see if it's leaking at the injectors, things like that.

[bbejj123]

I wish my single cam got better milage.

oh well.

it's a pos.

im in the same boat...haha gets around 260-290 on a single tank =/ running 91 it also idles at around 1500 rpmss way high i need to diagnose it sometime this summer haha

My old KA-T got 24-26mpg and my friends old red top (stock minus full 3" exhaust and FMIC....and 15psi) got 28-30mpg driving around. I am excited about getting my stock ass S14 SR in, haha.

[SHIFT_*grind*]

I think part of the explanation is that I have a GTiR T28, which is non-ball bearing and .86 A/R so it doesn't really boost until I get into the gas pedal. If I keep the revs low enough around town, it's almost like being N/A. I imagine if I had an S14 T28 it would get slightly lower mileage because it'd be harder to stay out of boost.

It's not so great for low-end torque and spirited driving, but great when you're paying $4/gallon. :D

I can do 27-30mpg with no highway driving.

High throttle low rpm shifting (<2200), coasting in neutral ect.

Also if you can stand it, slowing down and driving on the fwy at 55-65 will save a lot of gas too.

[scooz14]

im seeing 27 mixed in my single slammer. dont drive like an ass hole, and the good millage follows

[blackrms13]

the "freeway" speed can vary alot, in some states, its like 55mph, but here in cali is like 65mph, but usually we drive 70+, so theres a difference in the engine speed...thus consuming more fuel

[Lith]

I got 31mpg last weekend. Although that was 100% highway driving (Toronto to Montreal).

Usually on my stock KA I get 21-23mpg highway/city driving.

[touge dreamer]

I avg 24mpg on my stock KA. I don't see how you guys can get around 30mpg.

[MaD1337M3DRiV3r]

The thing that killed my gas milages was my walboro, i installed the nismo fpr and set it to the right psi.

I'm getting 25mpg mixed driving... s13 sr

[Lith]

I avg 24mpg on my stock KA. I don't see how you guys can get around 30mpg.

24mpg average is dead on (if you go by published figures from Nissan). I believe Nissan reported 21mpg city and 26mpg highway for our cars.
But I do believe that people can get more than that if they are on the highway and maintaining 55-65mph on cruise control (no AC or anything like that).

[LeftNutOfGowd]

Lets see 50 bucks for a ful tank gets me about 230 miles on my stock ka

[95KA-Turbo]

Yeah the interstate speed here is only 55. So I go 65 tops....granted there are plenty of people going 70+. When my car does the 28-30mpg on road trips I'm usually going ~75 because Interstate 95 is 65 and everyone goes fast as shit.

[stinky_180]

my s13 with my tune gets around 22mpg
my s14 completely stock gets around 25ish

[4bangers]

i get about 28mpg and sometime 30mpg, I keep mine below 2500rpm s14

[Siizzzoooo]

my last s14 kouki got over 30 mpgs, 400 miles were easy between fill ups

[kdashy]

my last s14 kouki got over 30 mpgs, 400 miles were easy between fill ups

Word, a properly maintained car w/ the right driving habits can do way over EPA estimates.

My average milage for today: 32.6 all city, tons of coasting in neutral to achieve this though.

[Anto]

ooooh you have a scangauge. i want one but its not obd1 compatible.

ive kept fuel logs on my ka since november 07, avg 22 to 27mpg. new o2 sensor does alot if its bad. ac doesnt take that much mpg if you drive normal, like .5 to 1mpg for me.
you want more mileage? get a tune on a stock ka. i hear you can get something like 35 mpg with a tune. stock kas run rich, tune = more power and less gas . of course its got to be in good condition beforehand

[SoguRacing]

pull out the dipstick. does the oil smell like gas? if so, you got ripped off even for $100 lol

[deuceforty]

i got 32 mpg last tank!!

442 miles on the tank!!

and only put in a little over 13 gallons!!

ka-t with stock t25

biggest improvement on gas mileage for me was taking off the clutch fan and putting on a lightweight flywheel

[nvstyles]

before i went to the track 2weeks ago and a FULL tune up. 26MPG on my sohc.

now after the track. 23 mpg... how the hell are yall pulling 28 to 30 highway?

[Jza]

Guys,
What did you guys get 26+mpg? I use 91Octane gas from 76. Shift ~2400rpm, top speed @ 70mph, SUPER gentle acceleration with very minor traffic city & Hwy drive. I gets 25.9mpg. This is done with new fuel filter, spark plugs and spark plug wires, K&N drop in filter and GReddy Ti-C exhaust.

I installed the Sun Voltage System GT and gain 1mpg. As a result, I have 26.9mpg for the best record. (For ppl. who interested in Sun voltage system, I'd suggest the MR version. I've tested that and feel the same as the GT except to have alittle more respone on the low end. Same gas milage gain).

[deuceforty]

like i said, i got the best gain on MPG by taking out the clutch fan and adding a lightweight flywheel

[1989rps13]

i get about 150miles in half a tank with my sr20det

is that good mileage??????

[irritatedmax]

i honestly think its just luck of the draw and how the car was cared for before you got it. you might baby the heck out of it and take great care of it now, but that isn't going to undo over 100,000 miles (for most of us) of damage being done before you got it.

on the flipside of that, i have never compression tested mine, it has a nasty oil leak, and has just a basic tune-up but still gets great mileage. i think you are doing pretty good at 26.9mpg.

[sr20det_s13]

Wow seems like you guy get better mileage than me its like 60 bucks a tank for me (i believe never filled up all the way) and i only get about 210 miles per tank! Sadface but yeah using fuel injector cleaners help out the mpgs at all?

[kdashy]

but yeah using fuel injector cleaners help out the mpgs at all?

If they're clogged yeah, Also inflating tires to max sidewall psi, alignment, clean air filter ect.

[beeracing s14]

my 180sx ka used to get 290 but when i changed to mobil 1 brown cap full synthetic .. im getting 325! and its automatic!

[irax]

my old s14 got way better gas milage at 80mph than 65, 400 a tank vs 355
could of been that stupid short ram that came with the car I don't know
my new s14 that was 100% stock except coilovers and s13 front end had even better. It got 485 on mostly highway at 65 and closer to 550 when i didn't let the rpms drop below 2500 rpm while moving

lower engine speed does not always equate to better fuel efficiency

550 miles per tank? how big is the s14 fuel tank? from empty to full, my s13 takes usually ~13 gallons. if s14's are the same, you are claiming to have gotten 42.3mpg.

[thelinja]

I'm getting 27 mpg and my commute is half city-half interstate. One time I got 38mpg driving to Chicago and back. I was going like 85-90mph the whole way. I dunno how I pulled that off. :rofl:

S14 tank is 17.2 gal. 550 miles per tank would be around 32 mpg which is attainable but unlikely.

[svensko]

My S14 KA24 with Injen intake gets pretty bad MPG, I don't even bother to calculate it. It burns oil and has 195K+ miles on it. :ugh:

However, the fuel is still affordable, it's paid for, and if i really start hurting I know i can spend a weekend replacing it with a fresh KA and probably double my mileage. :hsdance:

[mike-hkc]

any improvement? or let us know after you drive it a bit.

yeah it made a difference

[mike-hkc]

now i found out the stock headers has a leak

from this thread what people are saying is the DOHC gets better gas mileage AND more horsepower over the sohc? cause i get about 320 miles per tank on my s13 sohc and thats driving kindly

[SHIFT_*grind*]

24-25mpg average when I filled up yesterday.

[beeracing s14]

somebody mentioned to me in person that a ka24de brand new can still be bought somewhere in ca. does anybody know what shop it maybe?

[aziankingz]

i get about 13mpg city and 20mpg mixed driving...i fail..

[KiLLeR2001]

My SR gets 21mpg city driving.

[MAGILLA]

S14 tank is 17.2 gal. 550 miles per tank would be around 32 mpg which is attainable but unlikely.

I have gotten 480 out of one tank but I didn't push it cuz I hate walking to the gas station. I avg just over 30mpg on the hwy but that is with a j30 dif which I think got me over the 30mpg hump.

[S13Boosts]

damn when is ur sohc gonna die out? LOL 200+K sheesh!

[D1GP]

Stock DOHC with a SRI and 204k miles. I run mid-grade and get roughly 24-25mpg, half-city, half-freeway. I punch it a few times a day and drive an average of 80mph on the freeway. Roughly 300-320 miles per tank. Not bad but still jealous of the guys pulling 28-30mpg or so. I will be changing the spark plug wires, cap, rotor, temp sensor, and O2 sensor soon. Hopefully that will help.

[mike-hkc]

damn i just found out that my headers has a leak. will that have an effect on my mpg.

My 91 has a fresh built DE (12K on it now), 9:1 c/r, I run 10w-30 Mobil1, and 93 octane. I run a GT28R @ 9 psi with a ROM tune. I have never gotten over 350 to a tank. Before I put in Iridium plugs I would get 300-320 on a tank if I was lucky. This past week I got around 28 mpg, all highway with some stoplights every so often. The Iridiums made more of a difference in mileage than I thought for sure.

add fuel filter to that list too. They're fairly cheap and easy to change. The 300ZX fuel filter is what I use and it's actually cheaper than the 240SX filter. :keke:

[UNISA JECS]

I got 387 miles on 14.8 gallons of fuel with 90% highway so 26.1mpg with my S13 coupe with 225/40/18 and automatic transmission reving about ~3,400rpm ~90mph on a very long drive.

[UNISA JECS]

I plan on changing my final drive to 3.63 from the current 4.08 to see how much my highway milage improves.

[oscarsx]

im not really sure, but i can make it from my home to work with 15 bucks... and its an 2hour drive going and coming back, which i think is good... not to mention i have to come up on el cajon pass coming towards barstow, which can suck up your gas..


and did u guys know has is now 4.25 a gallon? blaahhhh... where is my skateboard!

[240cracker]

i get like 200miles on a full tank in my auto single cam for the daily.
piece of shit.

[krisdeezy]

that sounds like a new fuel pump if your gas gauge goes up and down ?...anyways how's the improvement on the seafoam and fuel filter ?

[1989rps13]

i get like 200miles on a full tank in my auto single cam for the daily.

wow thats shitty gas mileage i get around 150miles on a half tank and i think that is shitty gas mileage too:Ownedd: but now i feel better seeing your gas mileage:ughd:

[Wabash9000]

I drive my car hard all the time and I still get 24 city 27 highway.

[bunnathp]

my mpg is not that great. i filled up with 89 and got only about 190 miles on the tank. its ridiculous.

[Bud88]

93 octane
s13 sr
25mpg city........damn gas prices

[singlecamslam]

man this thread started out with a guy asking for help, and everyone is just showing off their gas mileage. Mines horrible, about 12 MPG. Changed fuel pressure regulator, coolent temp sensor, and nothing helped. This sucks. You guys make me jealous.

[rb25crazy]

i get around 25-28 mpg, socal s14 here... keep it below 2500 revs and do go to full throttle all the time will get you better gas mileage =D, but it's not worth it no fun =P

i get around 25-28 mpg, socal s14 here... keep it below 2500 revs and do go to full throttle all the time will get you better gas mileage =D, but it's not worth it no fun =P

wish i can keep it below 2.5k on freeway here....
fucking ppl all driving 80+...

[rb25crazy]

wish i can keep it below 2.5k on freeway here....
fucking ppl all driving 80+...

haha, dont drive on the fast lane then =P go to the right lane dude.

[95se]

22mpg city, 30hwy

[enkei2k]

my mpg is about 14-15....all local streets, bone stock except for the HKS exhaust...rarely rev past 3k except for getting on the highway...did a full tune up when i got the car less than 2 months ago.

[jinesz32]

with a full tank, i drove from oxnard to san diego, which is about 200 miles, and had a little less than half tank, just a LITTLE under half. i dont know how many mpg i get because my speedo dont worrk =/

[backroadtouge]

i use 93octane
only fill half a tank to keep car weight down, more mpg
im getting 400ish miles a tank, 40-55mph everywhere

keep good plugs in your car!

[jrocslider]

my dohc has 155k and i use 89 octane and i was getting about 17mpg and thought that sucked but didnt really know what else to do since i had changed everything when i put the motor in when i got the car. i work at o'reilly auto parts and with my discount i got an O2 sensor for like $20. after that i saw it go up to about 24 to 24 average.

[turbobrick]

I average around 30mpg around town with my SR. I havent taken it on any road trips so I dont know what it gets on the highway.

[BrownDogg]

Sorry for bumping an old thread but... When you guys are getting your mpgs... is that stock or modded?

Im getting about 22-23 city mpg getting on it quite a bit and my car is bone stock. stock exhaust and intake.

[Bushido]

380-400 miles per tank, consistently.

stock KA, with a leaky headgasket...

[LayNLow]

I get around 25-26 around town and 29-30 on the highway/interstate (hwy/int speed of 80-90ish) using prem. 95 ka with 220K miles with i/e

[HPKMotorsports3]

you need a tune up, bout 3 bottles of injector cleaner and a slap for not thinking of doing this in the first place

[amdnivram]

i get 11-12 mpg on the street with some highway mixed in.... did a full tune up and its still the same..... 200 miles a tank...... not sure whats wrong with my sohc besides being a sohc.
